Choose the Guillotine or the Diaper, Your Highness
I shoved at the solid chestplate of my original body with trembling hands. Fuck. It wouldn't budge. It felt like trying to push a stone wall. But the real princess, startled by my words, stumbled backward in a panic.
"S-sorry!"
Seeing that bandit-like face scrunched up in a tearful, fidgety mess made my blood pressure spike all over again. I staggered, steadying myself on my own.
"Don't make such a fuss. I'll walk again."
Her cold, tearless voice rang out. There was no time to rest. Margareta herself stepped forward and placed those damn three history books on top of my head.
"Resume the posture. Sway your hips. Keep your toes together."
I bit my lip hard and started walking again. That's when it happened. A heavy pressure bloomed in my lower abdomen. At first, I thought it was just the corset crushing my organs. But no. It was my bladder. Urine was filling it up.
Come to think of it, the moment I opened my eyes this morning, I'd been so horrified by the soul swap that I hadn't gone to the bathroom. On top of that, I'd been sweating buckets from extreme tension until just now. The fluids inside my body were screaming.
Hold it. It'll be over soon.
Back in my mercenary days, holding it for half a day during ambush operations was routine. I trusted my endurance. I clenched my lower abdomen tight and tightened my sphincter.
But I had underestimated this beautiful girl's body far too much.
"Stride! Didn't I tell you to narrow it!"
Smack! Margareta's fan struck my calf. The moment I flinched, a sharp jolt shot through my lower belly.
"Ugh...!"
Without thinking, I squeezed my thighs inward and twisted my body. The books on my head wobbled. I barely kept them from falling, but cold sweat poured down my spine.
I'm going crazy. My bladder was too small. Its capacity was laughably tiny compared to a man's body. And that merciless corset squeezing my waist—it was crushing my stomach downward, pressing my bladder like a water balloon on the verge of bursting.
"Why have you stopped again? Hold the hem of your skirt properly."
At Margareta's rebuke, I grabbed the dress hem with shaking fingers. I had to take a step. But I couldn't spread my legs. The moment I parted my thighs even a little, it felt like hot liquid would leak out between them.
"U-um... Head Maid..."
I opened my mouth with a trembling voice. The bathroom. I needed to go to the bathroom. But those words wouldn't come out. Was I supposed to say 'I need to pee' with this elegant, noble princess's mouth? Right in the middle of this room, while my original body stared at me with wide-open eyes? My meager pride wouldn't allow it.
"Do you have something to say?"
Margareta glared at me with cold eyes. Her gaze reminded me of the King's guillotine threat. 'If you lose your dignity, I'll have your head.' A princess twisting her legs and begging to go to the bathroom? That was a direct ticket to the guillotine.
"N-no, it's nothing. I'll... I'll walk..."
I forced myself to take a step. Hell had begun. Every time weight settled on the pointed toes of the glass slippers, a horrible vibration shot through my lower abdomen. Whenever I twisted my waist to sway my hips as Margareta instructed, it felt like my bladder was being crushed.
"Haa... ngh..."
Uncontrollable whimpers leaked from my lips. My breathing grew ragged, my face flushed as if it would burst. My vision flickered white. Every time the soft flesh of my inner thighs rubbed together, the friction heat felt maddeningly sensitive. My groin felt like it was about to explode. When I was a man, there was at least some sense of something holding it in, but now everything down there was wide open and completely uncontrollable. The hot sensation pooling at the tip of my urethra scraped at my nerves like crazy.
"Why is your posture like that again! Why are you walking with your knees turned inward! Don't walk like some cheap whore from a brothel!"
Margareta's sharp scolding rang out.
'No, fuck! My legs are closing because I have to pee!'
I screamed inside, but on the outside I only bit my lip harder. Hard enough to draw blood.
"Straighten your knees! Now!"
She approached and smacked the back of my knees with her fan. The two knees I'd been desperately keeping together were forced apart. And then it snapped. My endurance. My sphincter's control. My last shred of pride as a man. All of it broke in an instant.
"Ah... ah... no... ughhh...!"
The three books on my head tumbled to the floor with a clatter. I tried to collapse where I stood, but the rigid corset wouldn't let me bend at the waist. I could only stand there with my legs awkwardly spread, staring into empty space.
It was warm. No, it was hot. Uncontrolled hot liquid gushed from my lower opening. The sky-blue dress woven from the finest silk instantly darkened as it soaked through. The remaining yellow liquid that the fabric couldn't absorb streamed down my pale, smooth thighs.
Shhhhhhh—
In the silence that had filled the room, the horribly clear sound of water echoed. The urine that flowed down my calves soaked the glass slippers and spilled onto the plush, high-end carpet. A yellow, disgusting puddle rapidly spread across the floor.
"......"
It felt like time had stopped. Both Margareta and the real princess inside my original body. They all held their breath, staring at the puddle at my feet with horrified eyes.
Ah... aah...
My mind went completely blank. No thoughts came at all. The only thing proving I was still alive was the terrible warmth flowing down my thighs. Shame. An overwhelming shame unlike anything I'd ever felt crashed over me like a tidal wave, shattering my reason to pieces. Even when I'd rolled in an orc's shit pit on the battlefield, even when I'd been chased naked out of a tavern, I'd never felt anything like this. A grown adult man of twenty. A battle-hardened veteran. Had lost control and pissed himself.
"Huu... hic..."
Against my will, my eyes grew hot, and large tears began plopping from my big eyes. I didn't want to cry. Fuck. Where's my pride? How could I cry here? But this damned princess's body couldn't endure the extreme shame and fear, and was pouring out tears like a defense mechanism. My slender shoulders shook violently. The hands clutching the hem of my skirt had turned deathly white. I hung my head and cried endlessly. A suppressed, beast-like sob forced its way between my delicate lips.
"P-Princess...!"
The one who broke the silence was the sound of heavy, thudding footsteps. The real princess came rushing over, dragging my original bulky body.
"I-It's okay! Don't cry! These things happen! When I was little, if the corset was too tight, I'd hold it and hold it until I wet myself sometimes! It's true!"
What the hell was this crazy bitch saying? A hulking man with my vicious face was kneeling in front of me, flailing around and offering clumsy comfort. That booming baritone voice was advertising my humiliating accident to the entire room.
"Or... should I say I did it? That I peed on this carpet..."
"Shut... up... fuck, please just shut up...!"
I choked out the curse between sobs. Those so-called comforting words were rubbing salt into the gaping wound of my shattered pride. I'd rather she just stabbed me in the heart. It wasn't okay. None of it was okay. I didn't even have the strength to bite my tongue, so I just kept shaking, tears and snot pouring down.
"......Both of you, shut your mouths."
At that moment, Margareta, finally snapping out of her shock, gave a cold command. She pressed her fingers to her temple as if she had a headache and let out a deep sigh. Her gaze swept over my soaked silk dress and the puddle on the floor.
"Consider it a miracle that no other maids were in this room. If anyone else had seen, they would have reported it to His Majesty immediately, and both of you would have been dragged to the guillotine."
Margareta's chilling warning sent a shiver down my spine. It felt like my tears dried up instantly.
"Sir Knight. Immediately fetch the towels and water basin from that corner and clean the floor. We must erase every trace before the other maids come in."
"Y-yes! Understood!"
The real princess scampered off in a manner completely unsuited to that massive frame, grabbed a towel, and began furiously scrubbing the carpet. The sight of my original body sprawled on the floor wiping up my piss made reality feel like it was evaporating. Margareta removed her cloak and draped it over my trembling lower half. The moment someone else's warmth touched me, my body flinched even harder, writhing in shame.
"This was my oversight. I failed to account for the fact that Her Highness's body is incompatible with a male soul, resulting in diminished physiological control."
Margareta supported me and whispered softly.
"I'll have hot water drawn for a bath immediately. To the other maids, I'll say Her Highness sweated excessively and requires a bath."
"Haa... haa..."
I had no strength left to answer and could only gasp for breath. The sensation of cooling urine between my legs was horrifically vivid.
"And, Princess."
At Margareta's next words, I looked up at her with dazed eyes.
"From this afternoon onward, you will have to wear a diaper."
"...W-what?"
"A social tea party lasts at least three hours once you sit down. Getting up in the middle because you need the bathroom is a major breach of etiquette. Rather than losing control like today and wetting yourself in front of other nobles, it is far safer to wear a diaper underneath to conceal it."
It felt like I'd been clubbed over the head. A diaper. A fucking diaper. How old was I... No matter how much my outer appearance was that of a beautiful girl, she wanted me to live wearing a diaper?
"T-that's... ridiculous... I-I'm a twenty-year-old knight... ugh...!"
I tried to protest, but seeing how I couldn't even control my own sphincter, I had no words to refute her. Margareta showed no mercy.
The answer was already decided. I buried my face in my hands, my wet thighs trembling. Fuck. I really don't want to live anymore.
